<h2 id="rzahqadvrf">Advantages</h2>
|
|
<p>Windows environment on iSeries™ provides most of the capabilities of
|
|
running Microsoft® Windows on a PC-based server and provides
|
|
the following advantages over other computer systems.</p>
|
|
<p><span class="bold">Space savings</span></p>
|
|
<ul>
|
|
<li>There are fewer pieces of hardware to manage requiring less physical space.</li></ul>
|
|
<p><span class="bold">Greater accessibility and protection for your data</span></p>
|
|
<ul>
|
|
<li>An integrated Windows server uses iSeries disk storage, which is generally more
|
|
reliable than PC server hard disks.</li>
|
|
<li>You have access to faster iSeries tape drives for integrated server backups.</li>
|
|
<li><img src="delta.gif" alt="Start of change" />You can back up the entire Windows server as part of your iSeries server backup. This allows you to recover a failed server much faster
|
|
and easier than with typical file level recovery from Windows.<img src="deltaend.gif" alt="End of change" /></li>
|
|
<li>Integrated servers implicitly take advantage of superior data protection
|
|
schemes which exist in i5/OS™ such as RAID or drive mirroring.</li>
|
|
<li><img src="delta.gif" alt="Start of change" />Typical integrated server configurations have storage space
|
|
data spread across more iSeries disk drives than would be configured
|
|
in stand-alone (non-integrated) Windows server installations. This can frequently
|
|
provide better peak disk I/O capacity, since each server is not constrained
|
|
to few dedicated drives.<img src="deltaend.gif" alt="End of change" /></li>
|
|
<li><img src="delta.gif" alt="Start of change" />You can add additional disk storage to integrated servers without
|
|
shutting down the server.<img src="deltaend.gif" alt="End of change" /></li>
|
|
<li>It is possible to gain access to DB2® UDB for iSeries data through an enhanced Open Database
|
|
Connectivity (ODBC) device driver using iSeries Access. This device driver enables
|
|
server-to-server applications between integrated servers and i5/OS.</li>
|
|
<li>You have the ability to use an integrated server as a second tier in a
|
|
three-tier client/server application.</li>
|
|
<li><img src="delta.gif" alt="Start of change" />Virtual networking does not require additional LAN hardware
|
|
and provides communications between iSeries logical partitions, Integrated xSeries® Servers (IXSs), Integrated xSeries Adapters (IXAs), and iSCSI HBAs.<img src="deltaend.gif" alt="End of change" /></li></ul>
|
|
<p><span class="bold">Simplified administration</span></p>
|
|
<ul>
|
|
<li>User parameters, such as passwords, are easier to administer from i5/OS. You can create users and groups and enroll them from i5/OS to integrated
|
|
servers. This makes updating passwords and other user information from i5/OS easy.</li>
|
|
<li>Your computer system is less complicated thanks to the integration of
|
|
user administration function, security, server management, and backup and
|
|
recovery plans between the i5/OS and Microsoft Windows environments. You can
|
|
save your integrated server data on the same media as other i5/OS data and restore
|
|
individual files as well as i5/OS objects.</li></ul>
|
|
<p><span class="bold">Remote management and problem analysis</span></p>
|
|
<ul>
|
|
<li>You can sign on to i5/OS from a remote location and shut down or restart your
|
|
integrated server.</li>
|
|
<li>Since you can mirror integrated server event log information to i5/OS you can remotely
|
|
analyze Microsoft Windows errors.</li></ul>
|
|
<p><img src="delta.gif" alt="Start of change" /><span class="bold">xSeries server attached with an Integrated xSeries Adapter (IXA) or iSCSI HBA</span><img src="deltaend.gif" alt="End of change" /></p>
|
|
<ul>
|
|
<li>You have considerably more flexibility in configuring a full size xSeries than you have in configuring an IXS, an xSeries on a card.</li>
|
|
<li>Full size xSeries models are released more often, meaning that you
|
|
can get the most up-to-date Intel® processors and other hardware.</li>
|
|
<li>More PCI feature cards are available for full size xSeries servers
|
|
than for IXSs.</li></ul>
|
|
<p><img src="delta.gif" alt="Start of change" /><span class="bold">IBM® BladeCenter™ server attached via an iSCSI host
|
|
bus adapter</span><img src="deltaend.gif" alt="End of change" /></p>
|
|
<ul><img src="delta.gif" alt="Start of change" />
|
|
<li>Dense IBM BladeCenter packaging</li>
|
|
<li>New IBM BladeCenter models are released more frequently than IXS.</li><img src="deltaend.gif" alt="End of change" /></ul>
|
|
<p><span class="bold">Multiple servers</span></p>
|
|
<ul>
|
|
<li>Microsoft Cluster service allows you to connect multiple
|
|
servers into server clusters. Server clusters provide high-availability and
|
|
easy manageability of data and programs running within the cluster.</li>
|
|
<li>Without using LAN hardware, servers and logical partitions running on
|
|
the same iSeries have high-performance, secure virtual networking communications.</li>
|
|
<li>You can run multiple integrated servers on a single iSeries. Not only
|
|
convenient and efficient, this also gives you the ability to easily switch
|
|
to another up-and-running server if the hardware fails.</li>
|
|
<li>If you have multiple integrated servers installed on your iSeries, you can
|
|
define their Windows domain roles in a way that will simplify user enrollment
|
|
and access. For example, you might want to set up one of these servers as
|
|
a domain controller. Then you only have to enroll users to the domain controller
|
|
and users can log on from any Microsoft Windows machine on that domain.</li>
|
|
<li>An iSeries server's optical and tape drives can be shared with integrated
|
|
servers running on the iSeries.</li></ul>
|
|
<p><img src="delta.gif" alt="Start of change" /><span class="bold">Hot spare support</span><img src="deltaend.gif" alt="End of change" /></p>
|
|
<ul><img src="delta.gif" alt="Start of change" />
|
|
<li><img src="delta.gif" alt="Start of change" />Server integration and storage virtualization provide innovative
|
|
options that can enhance the reliability and recoverability of the Windows
|
|
server environment.<img src="deltaend.gif" alt="End of change" /></li>
|
|
<li><img src="delta.gif" alt="Start of change" />If the Windows server hardware fails, you can quickly and easily
|
|
switch the server's configuration to another hot spare xSeries server or IBM BladeCenter server without restarting your iSeries server. This may reduce the overall
|
|
number of PC servers needed to provide increased availability.<img src="deltaend.gif" alt="End of change" /></li>
|
|
<li><img src="delta.gif" alt="Start of change" />Hot spare support also adds flexibility by enabling one spare
|
|
server to be used to protect multiple production servers.<img src="deltaend.gif" alt="End of change" /></li><img src="deltaend.gif" alt="End of change" /></ul>
